mb/google/zork: Pass oscout system clk to rt5682 

In kernel clk for AMD SoCs we expose a generic clk by the name oscclk1.
This oscclk1 is a fixed 48Mhz frequency clk in RV.

In Zork oscout system clock is linked to rt5682 mclk. Setting mclk-name to
oscclk1 tells rt5682 driver its mclk is oscclk1.

BUG=b:158906189
TEST=rt5682 driver get the correct clk and tested audio playback
